SPECIFICATION forming part of Letters PatentNo. 279,361, dated June 12, 1883.

Application filed November 9, 1882. (No model.) I

To all, whom, 211; may concern Be it knownthat 1, CHARLES C. DUFFY, of Newport News, in the county of \Varwick and State of Virginia, have invented a new and useful Improvement in Railway Earth'Cars, of which the following is a full, clear, and exact description, reference being had to the annexed drawing, forming part of this specification.

This invention relates to railway-cars for hauling earth for building up and repairing road-beds; and the invention consists of the novel construction hereinafter described and claimed.

4 In the drawing is shown a perspective view of my invention.

The platform A of the car is constructed with a narrow plane portion B at the center, extending from one end to the other, and is divided transversely into three nearly equal parts by the cross-bars O D. Between the bars C D, on opposite sides of the narrow portion B, are arranged large chutes E F, which are to extend down between the front and rear wheels with a lateral inclination. Between the bars 0 D, respectively, and the ends of the car the plane portion B is made somewhat broader than at the center, and at opposite sides of these broader portions are arranged two small chutes, G H, which are located on opposite sides of the bolsters I J, respectively. The chutes are made small at the ends of the car to prevent their contact with the wheels. The series of chuteson each side of the car are provided with a door, K, which is hinged on a rod, L, and is adapted to close the mouths of the chutes. This door is provided with spring-bolts M, which are adapted to engage automatically with suitable keepers in the projecting ends orbottoms of the chutes, and to the bolts are connected chains N, which are attached to the rod D, which is to be turned with a crank, O, to withdraw the bolts. A

single movement of the said rod will withdraw all the bolts on a side at the same instant, when the weight of the earth in the chutes or pockets will force the door open. Any part of the load of earth that may remain on the plane portion B is to be scooped off into the chutes in the act of unloading the car. For the purpose of holding the doors open in this last operation they may be provided with one or more bars or levers attached to their lower edges on the inside of the large chutes, and these bars may be adapted to engage with suitable catches for holding the doors in a propped position.

If desired, the central portion, B, may be made inclined to opposite sides from a central line in order that the entire load may slide down the chutes when the bolts are released.

Having thus described my invention, what I claim, and desire to secureby Letters Patent,

1. A railway-car for hauling earth, &c., having the small chutes G H, located on opposite sides of the bolsters I J, respectively, and the large central chutes, E F, arranged be tween and supported by the cross-bars C D, combined with the doors K, which are made wide at the center and narrow at the ends to adapt them to close the two series of chutes, substantially as shownand described.

2. The combination, with the car having the two series of large and small chutes, and the doors K, made wide at the center and narrow at the ends, of the rod L, the spring-bolts M, and the chains N, connecting the bolts to the rod, whereby they may be released by winding the chains on the rod, substantially asshown and described.
